What Are Springtails?
- Scientific group: Collembola.
- Nature: Tiny, wingless, insect-like hexapods commonly found in soil and leaf litter.
- Size: Generally range from about 0.2 mm to 10 mm, depending on the species.
- Body structure: Have a segmented body, six legs and short antennae.
- Colour: Often pale or grey, although some species have yellow, orange, red or metallic colours.
- Movement: Many possess a spring-like organ called a furcula, which helps them leap away from danger.
- Skin: Some springtails have water-repellent surface structures that help prevent water from spreading across their bodies.
Habitat and Ecological Importance
- Habitat: Moist soil, leaf litter, forests and other environments rich in organic matter.
- Decomposition: Feed on fungi, microorganisms and decaying organic material, helping break down dead matter.
- Nutrient cycling: Support the recycling of nutrients and contribute to soil fertility.
- Soil health: Form an important part of soil ecosystems and help maintain ecological balance.
